As FIG. 14 shows, when the user operates the operation input block 1020 comprised of various operation buttons arranged on the cabinet or on the remote controller (not illustrated), the client terminal 1002 recognizes the input with the operation input block 1020 and sends the operation input signals entered by the user operation to the input data processing block 1021.

The input data processing block 1021 converts the operation input signals sent from the operation input block 1020 to special operation commands and sends them to the control block 1023 via the bus 1022.

The control block 1023 controls the movement of each circuit based on the operation commands and control signals given from the circuits connected via the bus 1022.

The display control block 1024 carries out the D/A conversion of the image data supplied via the bus 1022 and sends the converted analog image signals to the display block 1025.

The display block 1025, such a display device as an LCD for example, may be directly installed to the surface of the cabinet or may be a stand-alone device.

When the display block 1025 receives the results and various kinds of image data processed by the control block 1023 as analog image signals via the display control block 1024, it displays the images based on the received analog image signals.

The audio control block 1026 carries out the D/A conversion of the audio data supplied via the bus 1022 and sends the converted analog audio signals to the speaker 1027. The speaker 1027 outputs audio based on the analog audio signals supplied from the audio control block 1026.

The external recording media recording & playing-back block 1028 reads and plays back the content data recorded in CDs and the external recording media such as memory sticks (R) containing flash memory in the external package or it records the target content data in the external recording media.

When the external recording media recording & playing-back block 1028 reads the image data as the content data from an external recording media, it supplies the read image data to the display control block 1024 via the bus 1022.

Then, the display control block 1024 converts the image data read from the external recording media as the content data by the external recording media recording & playing-back block 1028 to the analog image signals and supplies them to the display block 1025.

When the external recording media recording & playing-back block 1028 reads the audio data as the content data from the external recording media, it supplies the read audio data to the audio control block 1026 via bus 1022.

Then, the audio control block 1026 converts the audio data read as the content data from the external recording media by the external recording media recording & playing-back block 1028 to the analog audio signals and supplies them to the speaker 1027.

The control block 1023 can send the content data read from the external recording media by the external recording media recording & playing-back block 1028 to the storage media 1029 in the client terminal 1002 via the bus 1022 and store the content data in the storage media 1029 (storing the content data in the storage media 1029 is hereinafter referred to as “ripping” also).

When the control block 1023 reads the image data or the video data as the content data from the storage media 1029, it provides the read image data to the display control block 1024 via the bus 1022.

When the control block 1023 reads the audio data as the content data from the storage media 1029, it supplies the read audio data to the audio control block 1026 via the bus 1022.

In addition to the above, the control block 1023 can record music data to the external recording media through the external recording media recording & playing-back block 1028 by reading the music data from the storage media 1029 and by transferring it to the external recording media recording & playing-back block 1028.

The broadcast signal receiving block 1030 receives the radiobroadcast waves sent from each radio station and supplies them to the tuner block 1031.

The tuner block 1031 extracts, under the control of the control block 1023, the radiobroadcast signals in the broadcasting frequency corresponding to the radio station specified through the operation input block 1020, for example, from the radiobroadcast waves received via the broadcast signal receiving block 1030, carries out the predetermined receiving processing and sends out the processed audio data to the audio control block 1026 via the bus 1022.

The audio control block 1026 converts the audio data given from the tuner block 1031 to the analog audio signals and sends them to the speaker 1027, by which it outputs from the speaker 1027 the audio of the radio program broadcast from the radio station and, thus, provides the user with the audio of the radio program.

The control block 1023 can also store the audio of the radio program by sending and storing the audio data obtained through the tuner block 1031 to the storage media 1029.

The control block 1023 can access the portal server 1003 and other servers from 1004 to 1007 on the network NT1000 through the connection with the network NT1000 via the communication control block 1032 and the network interface 1033 in sequence, through which it sends and receives various kinds of information and data with the portal server 1003 and other servers from 1004 to 1007.

The encoder/decoder block 1034 decodes the compressed content data received from the network NT1000 via the network interface 1033 and the communication control block 1032 in sequence or the compressed content data read from the storage media 1029 and the external recording media, and sends it to the display control block 1024 and the audio control block 1026.

The encoder/decoder block 1034 compresses the uncompressed content data read from the external recording media and the audio data supplied from the tuner block 1031, and sends the compressed content data to the storage media 1029.

Thus, the content data compressed by the encoder/decoder block 1034 is stored in the storage media 1029 under the control of the control block 1023.

The copyright management block 1035 generates the copyright management information corresponding to the content data downloaded from the network NT1000 via the network interface 1033 and the communication control block 1032 in sequence and the copyright management information corresponding to the content data read from the external recording media by the external recording media recording & playing-back block 1028.

The copyright management information generated by the copyright management block 1035 is registered to the storage media 1029 by associating it with the content data under the control of the control block 1023.

The copyright management block 1035 protects the copyright of the content data by properly updating the content of the copyright management information of the content data when it checks out the content data associated with the copyright management information between the storage media 1029 and a specified external recording media and when it checks in the content data associated with the copyright management information between the specified external recording media and the storage media 1029.

The page information generation block 1036 interprets the page information of the XML (extensible Markup Language) or HTML (Hyper Text Markup Language) files received from the network NT1000 via the network interface 1033 and the communication control block 1032 in sequence, generates the image data to display on the display block 1025 and sends the generated image data to the display control block 1024.

The authentication processing block 1037 carries out the authentication processing by sending, through the communication control block 1032 and the network interface 1033 in sequence, the authentication information to the portal server 1003 and other servers from 1004 to 1007 on the network NT1000 connected through the network interface 1033.

The authentication information storage block 1038 stores the authentication information necessary for the authentication processing block 1037 to access the portal server 1003 and other servers from 1004 to 1007.

The radiobroadcast display control block 1039 sends, via the communication control block 1032 and the network interface 1033 in sequence, the request signals to request the radiobroadcast information of the radiobroadcast currently received by the user to the radiobroadcast information distribution server 1006 corresponding to the radio station that is broadcasting the receiving radiobroadcast.

As a result, the radiobroadcast display control block 1039 not only receives the radiobroadcast information received from the radiobroadcast information distribution server 1006 on the network NT1000 via the network interface 1033 and the communication control block 1032 but also sends the received radiobroadcast information to the display control block 1024 to make the display block 1025 display the program name of the currently receiving radio program and the radiobroadcast information such as the title and artist name of the currently receiving music (which corresponds to the related information in the above-mentioned Embodiment 1).

(2-3) Configuration of Portal Server

Next, we are going to explain the hardware configuration consisting of the functional circuit block of the portal server 1003 using FIG. 15. The control block 1050 in the portal server 1003 controls the operation of each circuit connected through the bus 1051.

The communication control block 1052 sends to and receives from the client terminal 1002 and other servers from 1004 to 1008 various kinds of information through the network interface 1053 under the control of the control block 1050.

To the customer database block 1054, the user IDs (identification) information of the users who have made the agreement with the operators of the music related-service provision system 1000 are registered in association with their password information as the customer information.

The page information storage block 1055 stores the page information that is managed by the operator of the music-related service provision system 1000.

This page information is described in the XML language, for example, and includes the URL (Uniform Resource Locator) information for accessing the music data distribution server 1004, the product sales server 1005, the radiobroadcast information distribution server 1006 and the Internet radio server 1007.

When the authentication processing block 1056 receives the user ID and password information sent from the client terminal 1002 through the network interface 1053 and the communication control block 1052 in sequence, it checks, as the user authentication processing, whether the received user ID and password information is registered to the customer database block 1054 as the customer information.

When the authentication processing block 1056 completes the user authentication processing, it issues the portal authentication results (after-mentioned authentication session ID) showing the results of the user authentication processing and temporarily stores the issued portal authentication results in the authentication information storage block 1057.

When the results of the user authentication processing by the authentication processing block 1056 show that the user is the registered user, the control block 1050 sends the page information of the subscriber page stored in the page information storage block 1055 to the client terminal 1002 together with the portal authentication results via the communication control block 1052 and the network interface 1053 in sequence.

If the user was not authenticated as a registered user as a result of the user authentication processing by the authentication processing block 1056, the control block 1050 may be configured to send the authentication error information, together with the authentication error notice page information showing the error of the authentication stored in the page information storage block 1055, to the client terminal 1002 via the communication control block 1052 and the network interface 1053 in sequence.

When the authentication processing block 1056 receives, as a result of the execution of the authentication processing for the user from the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006, the portal authentication results (after-mentioned authentication ticket) obtained/sent from the client terminal 1002 of the user via the network interface 1053 and the communication control block 1052 in sequence, it compares the received portal authentication results with the portal authentication results of the user temporarily stored in the authentication information storage block 1057.

Thus, the authentication processing block 1056 verifies whether the portal authentication results comply with the registered portal authentication information as the authentication processing of what was received from the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006 and returns the authentication results showing the results of verification to the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006 via the communication control block 1052 and the network interface 1053 in sequence.

The communication control block 1092 sends to and receives from the client terminal 1002 and the portal server 1003 various kinds of information under the control of the control block 1090 via the network interface 1093.

To the customer database block 1094, the user ID and password information of the users who have made agreement with the operators of the product sales servers 1005 are registered by associating them with each other as the customer information. When the authentication processing block 1095 has the function of authenticating the user based on the portal authentication results issued by the portal server 1003 and sent from the client terminal 1002, however, the customer database block 1094 may not be built.

The page information storage block 1096 stores the page information of the package media sales pages introducing the package media such as CDs and DVDs for sale that are to be managed by the product sales server 1005.

For information, the page information of the package media sales pages is described in the XML language, which allows the user of the client terminal 1002 to select package media such as CDs or DVDs that the user wants to purchase.

When the control block 1090 receives the page information acquisition request signal requesting the page information of the package media sales pages sent from the client terminal 1002 via the network interface 1093 and the communication control block 1092 in sequence, it sends, based on the received page information acquisition request signal, the page information of the package media sales pages stored in the page information storage block 1095 to the client terminal 1002 via the communication control block 1092 and the network interface 1093 in sequence.

When the authentication processing block 1095 receives the user ID and password information of the user who uses the client terminal 1002, which is sent from the client terminal 1002, via the network interface 1093 and the communication control block 1092 in sequence, it verifies, as the user authentication processing, whether the received user ID and password information is registered to the customer database block 1094 as the customer information.

As a user authentication method different from what uses the user ID and password information, the authentication processing block 1095 receives the portal authentication results issued by the portal server 1003 and sent from the client terminal 1002 (after-mentioned authentication ticket) via the network interface 1093 and the communication control block 1092 in sequence, and it sends the received portal authentication results to the portal server 1003 via communication control block 1092 and the network interface 1093 in sequence.

Then, the authentication processing block 1095 receives, based on the transmission of the portal authentication results to the portal server 1003, the verification results sent as a result of the execution of the authentication processing (namely the above-mentioned verification processing) of the portal authentication results from the portal server 1003 via the network interface 1093 and the communication control block 1092 in sequence, and it verifies whether the user is the registered user who has made the agreement with the operator of the music-related service provision system 1000 based on the received verification results.

Thus, when the authentication processing block 1095 finishes the user authentication processing, it issues the server authentication results (after-mentioned service session ID) showing the results of the user authentication processing.

When the user is authenticated as the registered user as a result of the user authentication processing by the authentication processing block 1095, the control block 1090 sends the page information of the package media sales pages stored in the page information storage block 1096 for the subscriber to the client terminal 1002 together with the server authentication results via the communication control block 1092 and the network interface 1093 in sequence.

If the user is not authenticated as a registered user as a result of the user authentication processing by the authentication processing block 1095, the control block 1090 sends the authentication error to the client terminal 1002 together with the authentication error notice page information showing the error of authentication stored in the page information storage block 1096 via the communication control block 1092 and the network interface 1093 in sequence.

The authentication information storage block 1097 stores temporarily the server authentication results issued by the authentication processing block 1095 as well as various kinds of authentication information necessary for the authentication processing block 1095 to authenticate the user who uses the client terminal 1002.

The package media information storage block 1098 stores the information of multiple package media such as CDs and DVDs for sale (hereinafter referred to as the package media information) by associating it with the search keys including each package media ID.

When the search block 1099 receives, as a result of the transmission of the page information of the package media sales pages to the client terminal 1002, the media information request signal that requests the package media information of the package media such as a specific CD and DVD sent from the client terminal 1002 via the network interface 1093 and the communication control block 1092 in sequence, it extracts the search key for searching the specific package media from the received media information requests signal.

Then, based on the search key, the search block 1099 searches for the package media information of the specific piece of package media that complies with the search conditions shown by the search key from the multiple pieces of package media information in the package media information storage block 1098.

Thus, the control block 1090 sends the searched package media information to the client terminal 1002 via the communication control block 1092 and the network interface 1093 in sequence to show the package media information of the specific piece of package media to the user.

As a result, when the control block 1090 receives the purchase request signal requesting the purchase of the above-mentioned specific piece of package media sent from the client terminal 1002 via the network interface 1093 and the communication control block 1092 in sequence, it carries out the purchase processing such as the delivery of the specific piece of package media to the user who uses the client terminal 1002.

The control block 1090 also sends the billing information for the billing processes to the user who purchased the specific piece of package media to the billing server 1008 via the communication control block 1092 and the network interface 1093 in sequence to instruct the billing server 1008 to charge the user for the purchase of the specific piece of package media.

When the billing server 1008 completes the billing processes to the user, the control block 1090 sends the purchase completion page information that shows the completion of the purchase processing of the package media to the client terminal 1002 via the communication control block 1092 and the network interface 1093 in sequence.

(2-6) Functional Circuit Block Configuration of Radiobroadcast Information Distribution Server

Next, we are going to explain the hardware configuration of the functional circuit block of the radiobroadcast information distribution server 1006 using FIG. 18. The control block 1110 in the radiobroadcast information distribution server 1006 controls the operation of each circuit connected through the bus 1111.

The communication control block 1112 sends to and receives from the client terminal 1002 and the portal server 1003 various kinds of information under the control of the control block 1110 via the network interface 1113.

To the customer database block 1114, the user ID and password information of the users who have made agreement with the operators of the radiobroadcast information distribution servers 1006 is registered as the customer information by associating them with each other. When the authentication processing block 1115 has the function of authenticating the user based on the portal authentication results issued by the portal server 1003 and sent from the client terminal 1002, however, the customer database block 1114 may not be built.

The page information storage block 1116 stores the page information of the on-air list information distribution pages to be used for obtaining the radiobroadcast information (hereinafter specially referred to as the on-air list information) about the radio programs already broadcast by the radio stations supporting the radiobroadcast information distribution server 1006 that is to be managed by the radiobroadcast information distribution server 1006.

For information, the page information of the on-air list information distribution pages is described in the XML language, including the input boxes that allow the user of the client terminal 1002 to input the broadcast date/time information and the program names as the search keys for the on-air list information they want to obtain.

The on-air list information storage block 1117 stores the program names and the starting/ending times of the radio programs already broadcast by the radio stations supporting the radiobroadcast information distribution server 1006 as well as the on-air list information generated by listing the titles, the artist names and the starting times of the music broadcast in the radio programs.

When the control block 1110 receives the page information acquisition request signal requesting the page information of the on-air list information distribution pages sent from the client terminal 1002 via the network interface 1113 and the communication control block 1112 in sequence, it sends, based on the received page information acquisition request signal, the page information of the on-air list information distribution pages stored in the page information storage block 1116 to the client terminal 1002 via the communication control block 1112 and the network interface 1113 in sequence.

As a result, as the on-air list information request signal that requests the download of the on-air list information storing the search key for the on-air list information search, which the user wanted to obtain and which was entered on the page information of the on-air list information distribution pages, is sent from the client terminal 1002, the search block 1118 extracts the search key from the on-air list information request signal when it receives it via the network interface 1113 and the communication control block 1112 in sequence.

Then, based on such a search key, the search block 1118 searches for the given range that satisfies the search conditions shown by the search key in the entire on-air list information in the on-air list information storage block 1117 as the on-air list information that the user wants to obtain.

Thus, the control block 1110 sends the searched, acquisition-desired on-air list information to the client terminal 1002 via the communication control block 1112 and the network interface 1113 in sequence.

The now-on-air information storage block 1119 stores the now-on-air information including the program name, the starting and ending times of the radio program currently broadcast by the radio station supporting the radiobroadcast information distribution server 1006, and the title, the artist name and the starting time of the music broadcast currently broadcast in the radio program.

When the authentication processing block 1115 receives the user ID and password information of the user who uses the client terminal 1002, which is sent together with the now-on-air information request signal requesting the acquisition of the now-on-air information from the client terminal 1002, via the network interface 1113 and the communication control block 1112 in sequence, it verifies, as the authentication processing, whether the received user ID and password information is registered to the customer database block 1114 as the customer information.

As the user authentication method different from what uses the user ID and password information, the authentication processing block 1115 receives, the portal authentication results issued by the portal server 1003 and sent from the client terminal 1002 (after-mentioned authentication ticket) via the network interface 1113 and the communication control block 1112 in sequence and it sends the received portal authentication results to the portal server 1003 via the communication control block 1112 and the network interface 1113 in sequence.

Then, the authentication block 1115 receives, based on the transmission of the portal authentication results to the portal server 1003, the verification results sent from the portal server 1003 as a result of the execution of the authentication processing (namely the above-mentioned verification processes) of the portal authentication results via the network interface 1113 and the communication control block 1112 in sequence, and it verifies whether the user is the registered user who has made the agreement with the operator of the music-related service provision system 1000 based on the received verification results.

Thus, when the authentication processing block 1115 finishes the user authentication processing, it issues the server authentication results (after-mentioned service session ID) showing the results of the user authentication processing.

When the user is authenticated as the registered user as a result of the user authentication processing by the authentication processing block 1115, the control block 1110 sends the now-on-air information stored in the now-on-air information storage block 1119 to the client terminal 1002 together with the server authentication results via the communication control block 1112 and the network interface 1113 in sequence.

If the user is not authenticated as a registered user as a result of the user authentication processing by the authentication processing block 1115, the control block 1110 sends the authentication error to the client terminal 1002 together with the authentication error notice page information showing the error of authentication stored in the page information storage block 1116 via the communication control block 1112 and the network interface 1113 in sequence.

Thus, when the user requests for the acquisition of the now-on-air information, the control block 1110 verifies the authenticity of the user before distributing the now-on-air information. If it fails to verify the user's authenticity, it prevents the user from receiving the radiobroadcast information distribution service such as the now-on-air information distribution service provided by the radiobroadcast information distribution server 1006.

The authentication information storage block 1120 stores temporarily the server authentication results issued by the authentication processing block 1115 as well as various kinds of authentication information necessary for the authentication processing block 1115 to authenticate the user who uses the client terminal 1002.

(2-7) Processing Overviews of Servers

Next, we are going to explain briefly, using the sequence chart shown in FIGS. from 19 to 24, the processing to be carried out between the client terminal 1002 and the portal server 1003, the processing between the client terminal 1002 and other music data distribution servers 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006.

(2-7-1) User Authentication Processing between Client Terminal 1002 and Portal Server 1003

First of all, a description will be made on the user authentication processing to be carried out between the client terminal 1002 and the portal server 1003 using FIG. 19.

On the client terminal 1002 of the user who has an agreement with an operator of the music-related service provision system 1000, the control block 1023 starts the authentication request processing when the client terminal 1002 is turned on or the user presses a specific button on the operation input block 1020 and the input signal recognized by the operation input block 1020 is converted to a operation command in the input data processing block 1021.

When the control block 1023 starts the authentication request processing, it generates the connection request signal storing the authentication session ID temporarily stored in advance for the authentication information storage block 1038 and sends the generated connection request signal to the portal server 1003 via the communication control block 1032 and the network interface 1033 in sequence.

For information, the authentication session ID is the identification issued by the portal server 1003 for the purpose of identifying the status of the connection of communications (that is, a session) whenever communications are established between the client terminal 1002 and the portal server 1003 for the execution of various kinds of processing such as user authentication.

To such an authentication session ID, a given term of validity (e.g. about 1 minute) is set, based on the time of issuance by the portal server 1003, for its use for user authentication.

If the client terminal 1002 that obtained the authentication session ID from the portal server 1003 cannot provide the portal server 1003 with the authentication ID within the term of validity, the portal server 1003 judges that the communication specified by the authentication session ID was disconnected.

Thus, the portal server 1003 protects the authentication ID issued in the past from being abused by the user who has no agreement with an operator of the music-related service provision system 1 for the user authentication processing.

The authentication session ID temporarily stored in the authentication information storage block 1038 is what was issued by the portal server 1003 when communications were carried out between the client terminal 1002 and the portal server 1003 in order to carry out the user authentication processing in the past.

When the connection request signal is sent from the client terminal 1002 at the step SP1000, the control block 1050 of the portal server 1003 receives the connection request signal at the step SP1001 via the network interface 1053 and the communication control block 1052 in sequence, and it sends the authentication session ID stored in the received connection request signal to the authentication processing block 1056.

Then, the authentication processing block 1056 executes the user authentication processing under the control of the control block 1050 based on the authentication session ID received from the client terminal 1002 as the connection request signal.

As a result, if the authentication processing block 1056 could not authenticate that the user of the client terminal 1002 was a registered user due to the expiration of the validity of the authentication session ID received from the client terminal 1002, it sends the authentication error showing that the authentication failed to the client terminal 1002 via the communication control block 1052 and the network interface 1053 in sequence.

When the control block 1023 of the client terminal 1002 receives, at the step SP1002, the authentication error sent from the portal server 1003 via the network interface 1033 and the communication control block 1032 in sequence, it reads the user ID, the password and the device name stored in the authentication information storage block 1038, and sends the read user ID, password and device name to the portal server 1003 via the communication control block 1032 and the network interface 1033 in sequence.

At the step SP1003, the control block 1050 of the portal server 1003 receives the user ID, the password and the device name sent from the client terminal 1002 via the network interface 1053 and the communication control block 1052 in sequence, and it sends them to the authentication processing block 1056.

Under the control of the control block 1050, the authentication processing block 1056 checks whether the received user ID, password and device name are included in the customer information registered to the customer database block 1054 as the user authentication processing.

As a result, when the authentication processing block 1056 authenticates that the user of the client terminal 1002 is a registered user, it issues the authentication session ID, under the control of the control block 1050, for the current communication connection between the client terminal 1002 and the portal server 1003 as the portal authentication results, and it temporarily stores the issued authentication session ID in the authentication information storage block 1057.

Then, the control block 1050 sends the authentication session ID issued by the authentication processing block 1056 for the client terminal 1002 to the client terminal 1002 via the communication control block 1052 and the network interface 1053 in sequence.

At the step SP1004, the control block 1023 of the client terminal 1002 receives the authentication session ID sent from the portal server 1003 via the network interface 1033 and the communication control block 1032 in sequence, and it sends the received authentication session ID to the authentication processing block 1037.

The authentication processing block 1037 temporarily stores the received authentication session ID in the authentication information storage block 1038 under the control of the control block 1023.

Then, the control block 1023 sends the page information acquisition request signal for requesting the portal server 1003 for page information to the portal server 1003 together with the authentication session ID received from the portal server 1003 and temporarily stored in the authentication information storage block 1038 via the communication control block 1032 and the network interface 1033 in sequence.

At the step SP1005, the control block 1050 of the portal server 1003 receives the page information acquisition request signal and the authentication session ID sent from the client terminal 1002 via the network interface 1053 and the communication control block 1052 in sequence, and it sends the received authentication session ID to the authentication processing block 1056.

Under the control of the control block 1050, the authentication processing block 1056 carries out the user authentication processing to compare the received authentication session ID with what was issued to the client terminal 1002 and temporarily stored to the authentication information storage block 1057 in the above step SP1003.

As a result, when the authentication processing block 1056 authenticates that the user of the client terminal 1002 is a registered user at the step SP1006, it judges that the page information acquisition request from the client terminal 1002 is a legitimate request and extends the term of validity of the authentication session ID issued to the client terminal 1002.

Then, the control block 1050 reads the page information requested by the user from the page information storage block 1055 and sends the read page information to the client terminal 1002 together with the authentication session ID which term of validity was extended by the authentication processing block 1056 via the communication control block 1052 and the network interface 1053 in sequence.

At the step SP1007, the control block 1023 of the client terminal 1002 receives the page information sent from the portal server 1003 and the validity-extended authentication session ID via the network interface 1033 and the communication control block 1032 in sequence, and it not only sends the received page information to the page information generation block 1036 but also sends the validity-extended authentication session ID to the authentication processing block 1037.

The page information generation block 1036 generates, based on the page information supplied by the control block 1023, the image data of the page including the links to the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006, and it sends the generated image data to the display control block 1024.

Then, the display control block 1024 carries out the D/A conversion of the image data supplied from the page information generation block 1036 and sends the converted analog image signal to the display block 1025 to let the display block 1025 display the page of the portal server 1003 as the image of the analog image signal.

The authentication processing block 1037 stores temporarily, under the control of the control block 1023, the validity-extended authentication session ID received from the portal server 1003 by overwriting it on top of the original authentication session ID in the authentication information storage block 1038 to update the authentication session ID temporarily stored in the above-mentioned step SP1004 to what with a longer term of validity.

(2-7-2) User Authentication Processing between Client Terminal 1002 and Servers from 1004 to 1006

Next, we are going to explain the user authentication processing to be carried out between the client terminal 1002 and the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006.

There are two types of authentication processing between those devices. One type of user authentication processing is carried out, as mentioned in the above FIG. 19, by the client terminal 1002 by obtaining the page information from the portal server 1003 and then by accessing the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006 through the link embedded in the page information (hereinafter referred to as the indirect access authentication processing).

Another type is carried out by the client terminal 1002 by accessing directly, without obtaining the page information of the portal server 1003, the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006 based on URLs registered as book marks in advance (hereinafter referred to as the direct access authentication processing).

The indirect access authentication processing can be carried out in the same procedure irrespective of the combination between the client terminal 1002 and other 3 servers—the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006.

The direct access authentication processing can also be carried out in the same procedure irrespective of the combination between the client terminal 1002 and other 3 servers—the music data distribution server 1004, the product sales server 1005 or the radiobroadcast information distribution server 1006.

The only difference between the indirect access authentication processing and the direct access authentication processing is how to obtain the URL information that is used for the client terminal 1002 to access the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006. Once the URL information is obtained, both the indirect and the direct access authentication processing can be carried out in the same procedure.

In the following descriptions, therefore, the music data distribution server 1004 is picked up as a typical access destination server of the client terminal 1002 for simpler explanation, and we will explain the indirect access authentication processing and the direct access authentication processing by summarizing them as one type of user authentication processing.

First of all, at the step SP1010, the control block 1023 of the client terminal 1002 sends, in compliance with the URL information embedded in the page information as a link or the URL information already registered as a book mark, the service session ID read from the authentication information storage block 1038 to the music data distribution server 1004 together with the page information acquisition request signal requesting to obtain the page information of the music data distribution page (in the case of the product sales server 1005 and the radiobroadcast information distribution server 1006, it is the page information of the package media sales page and that of the on-air list information distribution page respectively) via the communication control block 1032 and the network interface 1033 in sequence.

For information, the service session ID is the identification information issued by the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006 accessed by the client terminal 1002 to identify the communication connection status of each server whenever the client terminal 1002 communicates with the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006 for the execution of various kinds of processing such as user authentication processing.

To such a service session ID, a given term of validity (e.g. about 1 minute) is set, based on the time of issuance by the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006, as is the case with the above-mentioned authentication session ID when it is used for user authentication.

If the client terminal 1002 that obtained the service session ID from each of the servers from 1004 to 1006 cannot provide the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006 with the service session ID within the term of validity, the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006, which issued the service session ID, judges that the communication specified by the service session ID has been disconnected.

Thus, the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006 protect the service session ID issued in the past from being abused by the user who has no agreement with an operator of the music-related service provision system 1 for the user authentication processing.

The service session ID temporarily stored in the authentication information storage block 1038 is what was issued by the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006 when communications were carried out between the client terminal 1002 and the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006 in order to carry out the user authentication processing in the past.

At the step SP1011, the control block 1070 of the music data distribution server 1004 receives the page information acquisition request signal and the service session ID sent from the client terminal 1002 via the network interface 1073 and the communication control block 1072 in sequence and it sends the received service session ID to the authentication processing block 1075.

Under the control of the control block 1070, the authentication processing block 1075 compares the received service session ID with what was already stored temporarily in the authentication information storage block 1077 to carry out the user authentication processing.

As a result, if the authentication processing block 1075 cannot authenticate that the user of the client terminal 1002 is a registered user because the term of the validity of the service session ID received from the client terminal 1002 has already expired, it judges that the acquisition request of the page information of the music data distribution page from the client terminal 1002 is not a legitimate request.

In this case, the control block 1070 sends the authentication error that shows the failure of the authentication and the shop code that identifies the music data distribution server 1004 to the client terminal 1002 via the communication control block 1072 and the network interface 1073 in sequence.

At the step SP1012, the control block 1023 of the client terminal 1002 receives the authentication error and the shop code sent from the music data distribution server 1004 via the network interface 1033 and the communication control block 1032 in sequence, recognizes that the user was not authenticated as a registered user by the music data distribution server 1040 from the received authentication error and stores temporarily the shop code received from the music data distribution server 1040 in the authentication information storage block 1038.

Then, the control block 1023 generates the authentication ticket issuance request signal which requests the portal server 1003 for the issuance of the authentication ticket to access the music data distribution server 1004 and sends the generated authentication ticket issuance request signal to the portal server 1003 together with the shop code of the music data distribution server 1004 and the authentication session ID already received from the portal server 1003 and temporarily stored in the authentication information storage block 1038 via the communication control block 1032 and the network interface 1033 in sequence.

At the step SP1013, the control block 1050 of the portal server 1003 receives the authentication ticket issuance request signal, the shop code and the authentication session ID sent from the client terminal 1002 via the network interface 1053 and the communication control block 1052 in sequence, and it sends them to the authentication processing block 1056.

The authentication processing block 1056 compares, under the control of the control block 1050, the received authentication session ID with what was already stored temporarily in the authentication information storage block 1057 to execute the user authentication processing.

As a result, if the authentication processing block 1056 cannot authenticate that the user of the client terminal 1002 is a registered user because the term of the validity of the authentication session ID received from the client terminal 1002 has already expired, it judges that the issuance request of the authentication ticket from the client terminal 1002 is not a legitimate request.

In this case, the control block 1050 sends the authentication error that shows the failure of the authentication to the client terminal 1002 via the communication control block 1052 and the network interface 1053 in sequence.

When the authentication processing block 1056 authenticates that the user of the client terminal 1002 is a registered user because the term of the validity of the authentication session ID received from the client terminal 1002 has not expired, it judges that the issuance request of the authentication ticket from the client terminal 1002 is a legitimate request. In this case, the control block 1050 advances the processing to the after-mentioned step SP1018.

At the step SP1014, when the control block 1023 of the client terminal 1002 receives the authentication error sent from the portal server 1003 via the network interface 1033 and the communication control block 1032 in sequence, it reads the user ID, the password and the device name stored in the authentication information storage block 1038 and sends the read user ID, password and device name to the portal server 1003 via the network interface 1033 and the communication control block 1032.

At the step SP1015, the control block 1050 of the portal server 1003 receives the user ID, the password and the device name sent from the client terminal 1002 via the network interface 1053 and the communication control block 1052 in sequence and it sends them to the authentication processing block 1056.

Under the control of the control block 1050, the authentication processing block 1056 checks whether the received user ID, password and device name are included in the customer information registered to the customer database block 1054 to execute the user authentication processing.

As a result, when the authentication processing block 1056 authenticates that the user of the client terminal 1002 is a registered user, it issues, under the control of the control block 1050, the authentication session ID for the current communication connection status between the client terminal 1002 and the portal server 1003 as a result of the portal authentication, and stores temporarily the issued authentication session ID in the authentication information storage block 1057.

The control block 1050 sends the authentication session ID issued to the client terminal 1002 by the authentication processing block 1056 to the client terminal 1002 via the communication control block 1052 and the network interface 1053 in sequence.

At the step SP1016, the control block 1023 of the client terminal 1002 receives the authentication session ID sent from the portal server 1003 via the network interface 1033 and the communication control block 1032 in sequence, and stores temporarily the received authentication session ID in the authentication information storage block 1038 using the authentication processing block 1037.

Then, the control block 1023 again generates the authentication ticket issuance request signal to request the portal server 1003 for the issuance of the authentication ticket and sends the generated authentication ticket issuance request signal to the portal server 1003 together with the shop code already stored temporarily in the authentication information storage block 1038 and the authentication session ID temporarily stored at this time via the communication control block 1032 and the network interface 1033 in sequence.

In this embodiment, the client terminal 1002 stores temporarily the shop code for the authentication information block 1038. In addition to it, the shop code can be sent to the portal server 1003 at the step SP1016 through the successive exchange of the shop codes at the time of the execution of the processing at the steps from SP1012 to 1016 between the client terminal 1002 and the portal server 1003 without storing them temporarily in the authentication information storage block 1038.

At the step SP1017, the control block 1050 of the portal server 1003 receives the authentication ticket issuance request signal, the shop code and the authentication session ID sent from the client terminal 1002 via the network interface 1053 and the communication control block 1052 in sequence, and it sends them to the authentication processing block 1056.

The authentication processing block 1056 compares, under the control of the control block 1050, the received authentication session ID with what is temporarily stored in the authentication information storage block 1057 to execute the user authentication processing.

As a result, if the authentication processing block 1056 authenticates that the user of the client terminal 1002 is a registered user because the term of the validity of the authentication session ID received from the client terminal 1002 has not expired, it judges that the issuance request of the authentication ticket from the client terminal 1002 is a legitimate request.

In the subsequent step SP1018, the authentication processing block 1056 issues, under the control of the control block 1050, the authentication ticket that permits access to the music data distribution server 1004 indicated by the shop code as the portal authentication results, based on the shop code and the authentication ticket issuance request signal received from the client terminal 1002 in the above-mentioned step SP1017.

At this stage, the authentication processing block 1056 stores temporarily, under the control of the control block 1050, the issued authentication ticket in the authentication information storage block 1057 and extends the term of validity of the authentication session ID issued to the client terminal 1002.

Then, the control block 1050 sends the authentication ticket issued by the authentication processing block 1056 to the client terminal 1002 together with the authentication session ID which term of validity has been extended by the authentication processing block 1056 via the communication control block 1052 and the network interface 1053 in sequence.

At the step SP1019, the control block 1023 of the client terminal 1002 receives the authentication ticket sent from the portal server 1003 and the validity-extended authentication session ID via the network interface 1033 and the communication control block 1032 in sequence, and it sends the received authentication session ID to the authentication processing block 1037.

Then, the control block 1023 sends the authentication ticket received from the portal server 1003 to the music data distribution server 1004 together with the authentication request signal via the communication control block 1032 and the network interface 1033 in sequence.

The authentication processing block 1037 stores temporarily, under the control of the control block 1023, the validity-extended authentication session ID received from the portal server 1003 by overwriting it on top of the original authentication session ID in the authentication information storage block 1038 to update the authentication session ID temporarily stored in the above-mentioned step SP1016 to what with a longer term of validity.

In the step SP1020, the control block 1070 of the music data distribution server 1004 receives the authentication request signal and the authentication ticket sent from the client terminal 1002 via the network interface 1073 and the communication control block 1072 in sequence.

Then, the control block 1070 sends the authentication ticket received from the client terminal 1002 to the portal server 1003 together with the authentication ticket verification request signal that requests to verify the authentication ticket via the network interface 1073 and the communication control block 1072 in sequence.

At the step SP1021, the control block 1050 of the portal server 1003 receives the authentication ticket verification request signal and the authentication ticket sent from the music data distribution server 1004 via the network interface 1053 and the communication control block 1052 in sequence, and it sends the received authentication ticket verification request signal and the authentication ticket to the authentication processing block 1056.

The authentication processing block 1056 compares, under the control of the control block 1050 and in compliance with the authentication ticket verification request signal, the received authentication ticket with what is temporarily stored in the authentication information storage block 1057 to verify the authentication ticket received from the music data distribution server 1004.

As a result, if the authentication processing block 1056 authenticates that the authentication ticket received from the music data distribution server 1004 is a normal authentication ticket, the control block 1050 sends the verification results showing its authenticity to the music data distribution server 1004 via the communication control block 1052 and the network interface 1053 in sequence.

At the step SP1022, the control block 1070 of the music data distribution server 1004 receives the verification results sent from the portal server 1003 via the network interface 1073 and the communication control block 1072 in sequence, and sends received verification results to the authentication processing block 1075.

Under the control of the control block 1070, the authentication processing block 1075 issues, based on the verification results, the service session ID for the current communication connection status between the client terminal 1002 and the music data distribution server 1004 as the server authentication results, and it stores temporarily the issued service session ID in the authentication information storage block 1077.

The control block 1070 sends the service session ID issued for the client terminal 1002 by the authentication processing block 1075 to the client terminal 1002 via the communication control block 1072 and the network interface 1073 in sequence.

At the step SP1023, the control block 1023 of the client terminal 1002 receives the service session ID sent from the music data distribution server 1004 via the network interface 1033 and the communication control block 1032 in sequence, and it stores temporarily the received service session ID in the authentication information storage block 1038 using the authentication processing block 1037.

Then, the control block 1023 sends the page information acquisition request signal requesting the page information of the music data distribution page to the music data distribution server 1004 together with the service session ID temporarily stored in the authentication information storage block 1038 via the communication control block 1032 and the network interface 1033 in sequence.

At the step SP1024, the control block 1070 of the music data distribution server 1004 receives the page information acquisition request signal and the service session ID sent from the client terminal 1002 via the network interface 1073 and the communication control block 1072 in sequence, and it sends the received service session ID to the authentication processing block 1075.

Under the control of the control block 1070, the authentication processing block 1075 compares the received service session ID with what was already issued to the client terminal 1002 and stored temporarily in the authentication information storage block 1077 at the above-mentioned step SP1022 to carry out the user authentication processing.

As a result, if the authentication processing block 1075 authenticates that the user of the client terminal 1002 is a registered user because the term of the validity of the service session ID received from the client terminal 1002 has not expired, it judges that the acquisition request of the page information of the music data distribution page from the client terminal 1002 is a legitimate request.

In this case, the control block 1070 proceeds to the operation in the next step SP1025 where it reads page information of the music data distribution page requested by the user from the page information storage block 1076, and it extends the term of validity of the service session ID issued to the client terminal 1002.

Then, the control block 1070 sends the page information of the music data distribution page read from the page information storage block 1076 to the client terminal 1002 together with the service session ID which term of validity was extended by the authentication processing block 1075 via the communication control block 1072 and the network interface 1073 in sequence.

At the step SP1026, the control block 1023 of the client terminal 1002 receives the page information of the music data distribution page and the validity-extended service session ID sent from the music data distribution server 1004 via the network interface 1033 and the communication control block 1032 in sequence, and it sends not only the received page information of the music data distribution page to the page information generation block 1036 but also the received service session ID to the authentication processing block 1037.

The authentication processing block 1037 stores temporarily, under the control of the control block 1023, the received validity-extended service session ID by overwriting it on top of the original service session ID in the authentication information storage block 1038 to update the service session ID temporarily stored in the above-mentioned step SP1023 to what with a longer term of validity.

The page information generation block 1036 generates the image data based on the page information of the music data distribution page and sends the generated image data to the display control block 1024.

The display control block 1024 carries out the D/A conversion of the image data supplied from the page information generation block 1036 and sends the converted analog image signal to the display block 1025 to let the display block 1025 display the music data distribution page as the image based on the analog signal.

(2-7-3) Music-Related Service Provision Processing

Next, we are going to explain, using FIGS. from 21 to 24, the music-related service provision processing when the user receives the music data distribution service, the product sales service and the radiobroadcast information distribution service using the page information of the music data distribution page, the package media sales page and the on-air list information distribution page that the client terminal 1002 obtained from the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006 in the user authentication processing procedure after the completion of the user authentication processing procedure executed between the client terminal 1002 and 3 servers—the music data distribution server 1004, the product sales server 1005 and the radiobroadcast information distribution server 1006—mentioned in FIG. 20.

(2-7-3-1) Music Data Distribution Service Provision Processing Procedure

First of all, we are going to explain, using FIG. 21, the music data distribution service provision processing procedure when the client terminal 1002 receives the music data distribution service from the music data distribution server 1004.

At the step SP1030, when the control command that selects part of music data distribution page, which is displayed on the display block 1025 as an image, is entered from the input data processing block 1021, the control block 1023 of the client terminal 1002 generates the download request signal that requests the download of the download-desired music data based on the inputted control command.

Then, the control block 1023 sends the download request signal to the music data distribution server 1004 together with the service session ID that was issued by the music data distribution server 1004 and temporarily stored in the authentication information storage block 1038 via the communication control block 1032 and the network interface 1033 in sequence.

In the step SP1031, the control block 1070 of the music data distribution server 1004 receives the download request signal and the service session ID sent from the client terminal 1002 via the network interface 1073 and the communication control block 1072 in sequence, and it sends the received service session ID to the authentication processing block 1075.

The authentication processing block 1075 compares, under the control of the control block 1070, the received service session ID with what was already stored temporarily in the authentication information storage block 1077 to execute the user authentication processing.

As a result, when the authentication processing block 1075 authenticates that the user who requested the download of the music data using the client terminal 1002 is a registered user, the control block 1070 advances its operation to the next step SP1032.

At the step SP1032, the search block 1079 searches for the music data, which the user wants to download and which complies with the search conditions shown by the search key, from multiple pieces of music data in the music data storage block 1078 based on the search key stored in the download request signal.

Then, when the search block 1079 searched for the music data successfully, the control block 1070 extends the term of validity of the service session ID issued to the client terminal 1002 by the authentication processing block 1075 and advances its operation to the next step SP1033.

At the step SP1033, the control block 1070 reads the music data, which the user wants to download and which was searched for by the search block 1079, from the music data storage block 1078, and it sends the read download-desired music data to the client terminal 1002 together with the service session ID which term of validity was extended by the authentication processing block 1075 via the communication control block 1072 and the network interface 1073 in sequence.

At the step SP1034, the control block 1023 of the client terminal 1002 receives the download-desired music data and the validity-extended service session ID sent from the music data distribution server 1004 via the network interface 1033 and the communication control block 1032 in sequence, stores the received music data in the storage media 1029 and sends the received service session ID to the authentication processing block 1037.

The authentication processing block 1037 stores temporarily, under the control of the control block 1023, the received validity-extended service session ID by overwriting it on top of the original service session ID in the authentication information storage block 1038 to update the contents of the service session ID already stored temporarily in the authentication information storage block 1038.

Thus, the client terminal 1002 can download the music data that the user wants to obtain, using the music data distribution service provided by the music data distribution server 1004.

(2-7-3-2) Product Sales Service Provision Processing Procedure

Next, we are going to explain, using FIG. 22, the product sales service provision processing procedure that the product sales server 1005 provides to the client terminal 1002.

At the step SP1040, when the control command that selects part of the package media sales page displayed on the display block 1025 as an image is inputted from the input data processing block 21, the control block 1023 of the client terminal 1002 generates the media information request signal that requests the package media information of a specific piece of package media corresponding to the inputted control command.

Then, the control block 1023 sends the media information request signal to the product sales server 1005 together with the service session ID that was already issued by the product server 1005 and is temporarily stored in the authentication information storage block 1038 via the communication control block 1032 and the network interface 1033 in sequence.

At the step SP1041, the control block 1090 of the product sales server 1005 receives the media information request signal and the service session ID sent from the client terminal 1002 via the network interface 1093 and the communication control block 1092 in sequence, and it sends the received service session ID to the authentication processing block 1095.

The authentication processing block 1095 compares, under the control of the control block 1090, the received service session ID with what was already stored temporarily in the authentication information storage block 1097 to execute the user authentication processing.

As a result, if the authentication processing block 1095 authenticates that the user who requested the package media information of the package media using the client terminal 1002 is a registered user, the control block 1090 advances the processing to the next step SP1042.

At the step SP1042, the search block 1099 searches for, based on the search key stored in the media information request signal, the package media information of the specific piece of package media that satisfies the search conditions shown by the search key from the multiple pieces of package media information in the package media information storage block 1098.

Then, when the search block 1099 searched for the package media information, the control block 1090 extends the term of validity of the service session ID issued to the client terminal 1002 by the authentication processing block 1095 and advances the processing to the next step SP1043.

At the step SP1043, the control block 1090 read, from the package media information storage block 1098, the package media information searched by the search block 1099 and sends the read package media information to the client terminal 1002 together with the service session ID which term of validity was extended by the authentication processing block 1095 via the communication control block 1092 and the network interface 1093 in sequence.

At the step SP1044, the control block 1023 of the client terminal 1002 receives the package media information and the validity-extended serviced session ID sent from the product sales server 1005 via the network interface 1033 and the communication control block 1032 in sequence, and it sends the received package media information to the page information generation block 1036, and the received service session ID to the authentication processing block 1037 respectively.

The authentication processing block 1037 stores temporarily, under the control of the control block 1023, the received and validity-extended service session ID by overwriting it on top of the original service session ID in the authentication information storage block 1038 to update the contents of the service session ID already stored temporarily in the authentication information storage block 1038.

The page information generation block 1036 generates the image data based on the package media information supplied by the control block 1023, converts the generated image data to the analog image signal with the display control block 1024 and sends it to the display control block 1025.

Thus, the control block 1023 makes the display block 1025 display the package media information as the image based on the analog image signal and advances the processing to the step SP1045.

At the step SP1045, when the control command that requests the purchase of the package media corresponding to the package media information displayed on the display block 1025 as an image is inputted from the input data processing block 1021, the control block 1023 generates the purchase request signal requesting the purchase of the package media in compliance with the inputted control command.

Then, the control block 1023 sends the purchase request signal to the product sales server 1005 together with the service session ID already received from the product sales server 1005 and temporarily stored in the authentication information storage block 1038 (namely, validity-extended service session ID) via the communication control block 1032 and the network interface 1033 in sequence.

At the step SP1046, the control block 1090 of the product sales server 1005 receives the purchase request signal and the service session ID sent from the client terminal 1002 via the network interface 1093 and the communication control block 1092 in sequence, and it sends the received service session ID to the authentication processing block 1095.

Under the control of the control block 1090, the authentication processing block 1095 compares the received service session ID with what was already stored temporarily in the authentication information storage block 1097 to carry out the user authentication processing.

As a result, if the authentication processing block 1095 authenticates that the user who requested the purchase of the package media using the client terminal 1002 is a registered user, the control block 1090 advances the processing to the next step SP1047.

At the step SP1047, the control block 1090 carries out the purchase processing to deliver the purchase-requested package media to the user of the client terminal 1002, sends the billing information for the billing processing to the user who purchased the package media to the billing server 1008 via the communication control block 1092 and the network interface 1093 in sequence, and it makes the billing server 1008 execute the billing processing for the purchase of the package media by the user.

The control block 1090 extends the term of validity of the service session ID issued to the client terminal 1002 by the authentication processing block 1095.

At the step SP1048, the control block 1090 sends, after the completion of the billing processing, the purchase completion page information that shows the completion of the purchase processing of the package media to the client terminal 1002 together with the service session ID which term of validity was extended by the authentication processing block 1095 via the communication control block 1092 and the network interface 1093 in sequence.

At the step SP1049, the control block 1023 of the client terminal 1002 receives the purchase completion page information sent from the product sales server 1005 and the validity-extended service session ID via the network interface 1033 and the communication control block 1032 in sequence, sends the received purchase completion page information to the page information generation block 1036 and transmits the service session ID received from the product sales server 1005 to the authentication processing block 1037.

The authentication processing block 1037 stores temporarily, under the control of the control block 1023, the received and validity-extended service session ID by overwriting it on top of the original service session ID in the authentication information storage block 1038 to update the contents of the service session ID already stored temporarily in the authentication information storage block 1038.

The page information generation block 1036 generates the image data based on the purchase completion page information supplied by the control block 1023, converts the generated image data to the analog image signal with the display control block 1024 and sends it to the display block 1025.

Then, the control block 1023 makes the display block 1025 display the purchase completion page as the image based on the analog image signal.

Thus, the client terminal 1002 allows the user to purchase the desired package media using the product sales service provided by the product sales server 1005.

(2-7-3-3) On-Air List Information Distribution Service Provision Processing Procedure

Next, using FIG. 23, we are going to explain the radiobroadcast information distribution service provision processing procedure when the client terminal 1002 receives the on-air list information distribution service in particular from the radiobroadcast information distribution server 1006 as the radiobroadcast information distribution service.

At the step SP1060, when the search key for the desired on-air list information search is entered in the input box on the on-air list information distribution page displayed as an image by the display block 1025 and the control command corresponding to the character string showing the entered search key is entered from the input data processing block 1021, the control block 1023 of the client terminal 1002 generates, based on the entered control command, the on-air list information request signal requesting the download of the desired on-air list information.

Then, the control block 1023 sends the on-air list information request signal to the radiobroadcast information distribution server 1006 together with the service session ID already issued by the radiobroadcast information distribution server 1006 and temporarily stored in the authentication information storage block 1038 via the communication control block 1032 and the network interface 1033 in sequence.

At the step SP1061, the control block 1110 of the radiobroadcast information distribution server 1006 receives the on-air list information request signal and the service session ID sent from the client terminal 1002 via the network interface 1113 and the communication control block 1112 in sequence, and it sends the received service session ID to the authentication processing block 1115.

The authentication processing block 1115 compares, under the control of the control block 1110, the received service session ID with what was already stored, temporarily in the authentication information storage block 1120 to carry out the user authentication processing.

As a result, when the authentication processing block 1115 authenticates that the user who uses the client terminal 1002 and requested the on-air list information is a registered user, the control block 1110 advances the processing to the next step SP1062.

At the step SP1062, the search block 1118 searches for, based on the search key stored in the on-air list information request signal, a given range of on-air information satisfying the search conditions of the search key as the desired on-air list information in the entire on-air list information in the on-air list information storage block 1117.

Then, when the search block 1118 searched for the on-air list information, the control block 1110 extends the term of validity of the service session ID issued to the client terminal 1002 by the authentication processing block 1115 and advances its operation to the next step SP1063.

At the step SP1063, the control block 1110 reads the on-air list information searched for by the search block 1118 from the on-air list information storage block 1117, and it sends the read on-air list information to the client terminal 1002 together with the service session ID which term of validity was extended by the authentication processing block 1115 via the communication control block 1112 and the network interface 1113 in sequence.

At the step SP1064, the control block 1023 of the client terminal 1002 receives the on-air list information sent from the radiobroadcast information distribution server 1006 and the validity-extended service session ID via the network interface 1033 and the communication control block 1032 in sequence, sends the received on-air list information to the page information generation block 1036 and transmits the service session ID received from the radiobroadcast information distribution server 1006 to the authentication processing block 1037.

The authentication processing block 1037 stores temporarily, under the control of the control block 1023, the received and validity-extended service session ID by overwriting it on top of the original service session ID in the authentication information storage block 1038 to update the contents of the service session ID already stored temporarily in the authentication information storage block 1038.

The page information generation block 1036 generates the image data based on the on-air list information supplied from the control block 1023, converts the generated image data to the analog image signal with the display control block 1024 and sends it to the display block 1025 to make the display block 1025 show the on-air list information as an image based the analog image signal.

Thus, the client terminal 1002 allows the user to obtain the desired on-air information using the radiobroadcast information distribution service provided by the radiobroadcast information distribution server 1006.

(2-7-3-4) Now-on-Air Information Distribution Service Provision Processing Procedure

Next, we are gong to explain the radiobroadcast information distribution service provision processing procedure when the client terminal 1002 receives the on-air list information distribution service in particular from the radiobroadcast information distribution server 1006 as the radiobroadcast information distribution service.

However, the radiobroadcast information distribution server 1006 that provides the now-on-air information is prepared for each radio station (call sign).

The client terminal 1002 may not store the URL information of the radiobroadcast information distribution server 1006 supporting each radio station at the default state.

Therefore, we will explain the radiobroadcast information distribution service provision processing procedure by giving an example of the case that the portal server 1003 manages the URL information of each radiobroadcast information distribution server 1006 by call sign.

In the radiobroadcast information distribution service provision processing procedure, it is assumed that the authentication information storage block 1038 does not store temporarily the authentication session ID when the client terminal 1002 requests the portal server 1003 for the frequency information that shows the broadcasting frequency in order to automatically preset the broadcasting frequency for each radio station. The client terminal 1002, therefore, is to send the user ID, the password and the device name to the portal server 1003.

At the step SP1070, when the operation command requesting to automatically preset the broadcasting frequency of each radio station is entered from the input data processing block 1021, the control block 1023 of the client terminal 1002 sends the frequency information request signal requesting to obtain the frequency information of receivable broadcasting frequency of each radio station to the portal server 1003 together with the area code entered by the user, the user ID, the password and the device name stored in the authentication information storage block 1038 via the communication control block 1032 and the network interface 1033 in sequence.

At the step SP1071, the control block 1050 of the portal server 1003 receives the frequency information request signal, the area code, the user ID, the password and the device name sent from the client terminal 1002 via the network interface 1053 and the communication control block 1052 in sequence, and it sends the user ID, the password and the device name to the authentication processing block 1056 from the received information.

Under the control of the control block 1050, the authentication processing block 1056 compares the received user ID, password and device name with the customer information registered to the customer database block 1054 to carry out the user authentication processing.

As a result, when the authentication processing block 1056 authenticates that the user of the client terminal 1002 is a registered user and judges that the acquisition request of the frequency information from the client terminal 1002 is a legitimate request, it issues, under the control of the control block 1050, the authentication session ID for the communication connection between the current client terminal 1002 and the portal server 1003, and it temporarily stores the issued authentication session ID in the authentication information storage block 1057.

Then, the control block 1050 advances the processing to the next step SP1072, where it searches for, lists and reads the frequency information corresponding to the area code, radio station name and call sign from the list of multiple kinds of frequency information, radio station names and call signs in the frequency information storage block 1058 based on the area code received from the client terminal 1002.

The control block 1050 sends the frequency information, radio station names and call signs that it listed and read from the frequency information storage block 1058 to the client terminal 1002 together with the authentication session ID issued by the authentication processing block 1056 to the client terminal 1002 at the above-mentioned step SP1071 via the communication control block 1052 and the network interface 1053 in sequence.

At the step SP1073, the control block 1023 of the client terminal 1002 receives the list of the frequency information, the radio station names and the call signs sent from the portal server 1003 via the network interface 1033 and the communication control block 1032 in sequence, sends the authentication session ID received from the portal server 1003 to the authentication processing block 1037 and transmits the list of the frequency information, the radio station names and the call signs to the display control block 1024.

The authentication processing block 1037 temporarily stores, under the control of the control block 1023, the received authentication session ID in the authentication information storage block 1038.

The display control block 1024 sends the list of the frequency information, the radio station names and the call signs provided by the control block 1023 to the display block 1025 so that the display block 1025 can display the list.

The control block 1023 stores, based on the selection command input from the input data processing block 1021 at this time the selected frequency information, radio station names and call signs in the storage media 1029 as presets and advances the processing to the next step SP1074.

At the step SP1074, the control block 1023 controls the tuner block 1031 in compliance with the tuning control command entered from the input data processing block 1021 so that it extracts the radiobroadcast signal of the radiobroadcast that is broadcast in the frequency corresponding to the tuning control command from the broadcast waves.

Thus, the tuner block 1031 extracts the radiobroadcast signal that is broadcast in the broadcasting frequency from the radiobroadcast waves received by the broadcast signal receiving block 30, carries out given receiving processing such as decoding and sends the audio data obtained from the processing to the audio control block 1026.

The audio control block 1026 converts the audio data given by the tuner block 1031 to the analog audio signal and sends it to the speaker 1027, which outputs the audio of the selected radio program.

At the step SP1075, the radiobroadcast display control block 1039 reads, under the control of the control block 1023, the stored call sign in accordance with the frequency information showing the broadcasting frequency corresponding to the above-mentioned tuning control command and sends the read call sign to the portal server 1003 together with the authentication session ID already stored temporarily in the authentication information storage block 1038 via the communication control block 1032 and the network interface 1033 in sequence.

At the step SP1076, the control block 1050 of the portal server 1003 receives the call sign and the authentication session ID sent from the client terminal 1002 via the network interface 1053 and the communication control block 1052 in sequence, and it sends the received authentication session ID to the authentication processing block 1056.

The authentication processing block 1056 compares, under the control of the control block 1050, the received authentication session ID with what was already stored temporarily in the authentication information storage block 1057 to execute the user authentication processing.

As a result, when the authentication processing block 1056 authenticates that the authentication ID received from the client terminal 1002 is still valid and that the user who used the client terminal 1002 to send the call sign is a registered user, the control block 1050 advances the processing to the next stage SP1077.

At the step SP1077, the control block 1050 searches for, based on the call sign received from the client terminal 1002, the URL information linked to the call sign from among multiple pieces of URL information in the URL storage block 1059.

The control block 1050 extends the term of validity of the authentication session ID issued for the client terminal 1002 with the authentication processing block 1056.

Then, the control block 1050 reads the searched URL information from the URL storage block 1059 and sends the read URL information to the client terminal 1002 together with the authentication session ID which validity was extended by the authentication processing block 1056 via the communication control block 1052 and the network interface 1053 in sequence.

At the step SP1078, the control block 1023 of the client terminal 1002 receives the URL information and the validity-extended authentication session ID sent from the portal server 1003 via the network interface 1033 and the communication control block 1032 in sequence, sends the received authentication session ID to the authentication processing block 1037 and transmits the URL information to the radiobroadcast display control block 1039.

Under the control of the control block 1023, the authentication processing block 1037 stores temporarily the received and validity-extended authentication session ID in the authentication information storage block 1038 by overwriting it on top of the original authentication session ID to update the contents of the authentication session ID already stored temporarily in the authentication information storage block 1038.

The radiobroadcast display control block 1039 temporarily stores, under the control of the control block 1023, the URL information given by the control block 1023 by associating it with the call sign stored in the storage media 1029.

The radiobroadcast display control block 1039 sends, under the control of the control block 1023, the now-on-air information request signal that requests the now-on-air information in accordance with the URL information temporarily stored in the storage media 1029 together with the service session ID already received from the radiobroadcast information distribution server 1006 and temporarily stored in the authentication information storage block 1038 via the communication control block 1032 and the network interface 1033 in sequence.

In the radiobroadcast information distribution service provision processing procedure, the processing that sends the now-on-air information request signal and the service session ID to the radiobroadcast information distribution server 1006 from the client terminal 1002 at the step SP1078 corresponds to the processing at the step SP1010 mentioned in FIG. 20.

Therefore, in the radiobroadcast information distribution service provision processing procedure, the user authentication processing similar to those at the steps from SP1011 to SP1013 and those from SP1018 to SP1022 explained in FIG. 20 are to be executed in sequence in the client terminal 1002, the radiobroadcast information distribution server 1006 and the portal server 1003 after the processing at the step SP1078. Then, the processing proceeds to the next step SP1079.

At the step SP1079, the radiobroadcast display control block 1039 of the client terminal 1002 sends, under the control of the control block 1023, the now-on-air information request signal to the radiobroadcast information distribution server 1006, in accordance with the URL information temporarily stored in the storage media 1029, together with the service session ID already received from the radiobroadcast information distribution server 1006 and temporarily stored in the authentication information storage block 1038 via the communication control block 1032 and the network interface 1033 in sequence.

At the step SP1080, the control block 1110 of the radiobroadcast information distribution server 1006 receives the now-on-air information request signal and the service session ID sent from the client terminal 1002 via the network interface 1113 and the communication control block 1112 in sequence, and it sends the received authentication session ID to the authentication processing block 1115.

The authentication processing block 1115 compares, under the control of the control block 1110, the received service session ID with what was already stored temporarily in the authentication information storage block 1120 to execute the user authentication processing.

As a result, if the authentication processing block 1115 authenticates that the user of the client terminal 1002 is a registered user, it judges that the acquisition request of the now-on-air information from the client terminal 1002 is a legitimate request.

Then, if the authentication processing block 1115 authenticates that the user of the client terminal 1002 is a registered user, the control block 1110 extends the term of validity of the service session ID issued by the authentication processing block 1115 to the client terminal 1002, and it advances the processing to the next step SP1081.

At the step SP1081, the control block 1110 reads the now-on-air information from the now-on-air information storage block 1119 and sends the read now-on-air information to the client terminal 1002 together with the service session ID which term of validity was extended by the authentication processing block 1115 via the communication control block 1112 and the network interface 1113 in sequence.

At the step SP1082, the control block 1023 of the client terminal 1002 receives the now-on-air information and validity-extended service session ID from the radiobroadcast information distribution server 1006 via the network interface 1033 and the communication control block 1032 in sequence, sends the received service session ID to the authentication processing block 1037 and transmits the now-on-air information to the radiobroadcast display control block 1039.

The authentication processing block 1037 stores temporarily, under the control of the control block 1023, the received validity-extended service session ID by overwriting it on top of the original service session ID in the authentication information storage block 1038 to update the contents of the service session ID temporarily stored in the authentication information storage block 1038.

The radiobroadcast display control block 1039 sends the now-on-air information given by the control block 1023 to the display block 1025 via the display control block 1024 so that the display block 1025 can display the now-on-air information of the radio program of the currently receiving radiobroadcast.

In such radiobroadcast information distribution service provision processing procedure, the client terminal 1002 requests repeatedly and regularly the now-on-air information in the step SP1079 later, and the radiobroadcast information distribution server 1006 receives the acquisition request from the client terminal 1002 to carry out the processing at the steps SP1080 and SP1081 in sequence.

Thus, the client terminal 1002 can show the name of the radio program of the currently receiving radiobroadcast, the program broadcast starting time, the program broadcast ending time, the title of the music currently broadcast in the radio program, the artist name and the music broadcast starting time on the display block 1025 of the client terminal 1002 as the now-on-air information by updating them momently.
